IMPROVEMENT IN THREAD-CUTTERS.

Specification forming part of Letters Patent No. 141,235, dated July 29,1873 application filed June 19, 1873.

To all whom it may concern:

Be it known that I, MARY JANE PITRAT, of Gallipolis, in the county ofGallia and in the State of Ohio, have invented a certain new and usefulThread-Cutter; and I do hereby declare that the following is a full,clear, andexact description thereof, reference being bad to theaccompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in constructing a thread-cutter, tobe used in combination with a sewing-thimble, formed of a spring, with acutting-edge, affixed to a springband, by which the device is secured tothe thimble, as will more fully hereinafter appear.

To enable those skilled in the art to make and use my invention, I willnow describe its construction and operation.

In the drawings, Figure 1 is an enlarged side view of my inventionattached to a thimble. Fig. 2 is a front View of the same, and Fig. 3 isa modified form of my invention.

A represents the thimble. B is the springba-nd, embracing the thimbleand securing the thread-cutter on the thimble. It is preferably made ofsteel; and it may be suitably ornamented by polishing, plating, washing,engraving, &c. The ends of this band do not touch, and so allowing theband to be adjustable to any size of thimble. In the middle of this bandB spring 0 is firmly secured by its middle, while its end a is turned upand provided with a point, b, and cutting-edge c that projects partlythrough a slot, d, in the other end, 0, of the spring I can make asimpler thread-cutter than the one just described by dispensing withspring 0 and constructing the band B of wire, making one of its endsbarbed, as in Fig. 3, where the cutting-surface is shown between thepoints a and b of the barbed end.

My invention is secured to any thimble used in sewing by slipping thespring-band B over the taper end and forcing the band to the rim of thethimble. When thus placed on the thimble, and it on the sewers finger,any sewingthread may be quickly and easily out by drawing taut thethread to be severed with one hand and applying the cutting-edge of thedevice to the thread with the other hand.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The detachable thread-cutter for sewingthimbles, consisting of thespring-band B and spring-cutter O, substantially as shown.

2. The thread-cutter, constructed as herein described, in combinationwith a sewing-thimble.

In testimony that I claim the above-described certain new and usefulthread-cutter I have hereunto signed my name this 12th day of June,1873.

MARY JANE PITRAT.
